Answer
$39$ square feet.
Work Step by Step
The area of a rectangle can be calculated as:
$T=a\times b$
The area of this figure can be calculated as:
Area of the big rectangle (with sides of $2+5$ and $9+3$) minus the area of the small rectangle (with sides of 5 and 9):
$T=(2+5)\times(9+3)-(5\times9)=7\times12-45=84-45=39$ square feet.
